A genus of nonmotile, aerobic bacteria (family Moraxellaceae) containing Gram-negative or -variable coccoid or short rods, or cocci, often occurring in pairs. Spores are not produced. These bacteria grow on ordinary media without the addition of serum. They are oxidase-negative and catalase-positive; carbohydrates are oxidized or not attacked at all, and arginine dihydrolase is not produced. They are a frequent cause of nosocomial infections; often resistant to many antibiotics, they can also cause severe primary infections in immunocompromised people. The type species is A. calcoaceticus. SYN: Lingelsheimia.
- A. calcoaceticus a species of bacteria originally found in a quinate enrichment; strains of this organism previously identified as Bacterium anitratum were found in the genitourinary tract; it is the type species of the genus A.. SYN: Lingelsheimia anitrata.
